Designed for vehicle emission measurements Airmodus A23 Condensation Particle Counter is a user-friendly tool for all applications where counting aerosol particles larger than 23 nm is a necessity. The A23 CPC is compliant with the Particle Measurement Protocol (PMP) for EURO 5/6. It fulfills the requirements of UN/ECE R49 and UN/ECE R83.
A versatile particle counter The A23 can be used both as a stand-alone instrument for measuring the total particle number concentration, and as a counter in different kinds of aerosol measurement systems. It is easy to use and handle. All settings can be quickly adjusted from a handy touch screen, which also displays the current concentration reading and instrument diagnostics.
The A23 is also compatible with the Airmodus Particle Size Magnifier A10. Benefits of the A23
- The saturator is made of robust and inert stainless steel in order to ensure stable operation
- Narrow pulse width for higher counting accuracy - Easy to use touch screen - Improved usability and design: all connections optimized for easy access
